I asked him how eating butter gets butyrate into the colon, since it’s absorbed before it gets to the colon. This link he posted says to eat starch and fiber. Another link he sent me also said to eat starch and fiber. In fact, he agrees:

@fanaticcook1/ SCFA's like butyrate/acetate/propionate are produced in large intestine by bacterial fermentation of dietary fiber. Agreed!

Butter enemas–remind me of the film “Last Tango in Paris,” w/ its memorable use if a stick of butter…. And re colon cancer, it’s no joke, as you point out. I know several people (men & women, young & old) who have died from it.
